1990 rude 90 hp TNT making crunchy sound

[riopga]

Trim portion seems to work fine both directions. But when it gets to the tilt part of travel going up it sometimes almost sounds crunchy. It went up, but didn't want to come back down. Pressing on the motor while running the down switch got it moving.
